Oscillating positive expiratory pressure (OPEP) devices are intended to facilitate sputum clearance in chronic obstructive pulmonary disease (COPD), but there is uncertainty as to their place in treatment pathways. We aimed to review the existing literature to establish the evidence base for their use. ⋯ CRD 42016041835.

Idiopathic pulmonary fibrosis (IPF) is a lung disease of unknown cause characterised by progressive scarring, with limited effective treatment and a median survival of only 2-3 years. Our aim was to identify potential occupational and environmental exposures associated with IPF in Australia. ⋯ The burden of IPF could be reduced by intensified tobacco control, occupational dust control measures and elimination of asbestos at work.

Domiciliary non-invasive ventilation (NIV) effectively reduces arterial carbon dioxide pressure (PaCO2) in patients with stable hypercapnic chronic obstructive pulmonary disease, but a consistent percentage of them may remain hypercapnic. We hypothesised that extracorporeal CO2 removal (ECCO2R) may lower their PaCO2 Ten patients hypercapnic despite ≥6 months of NIV underwent a 24-hour trial of ECCO2R. ⋯ Time to return to baseline after interruption ranged 48-96 hours. In four patients, mechanical events led to ECCO2R premature interruption, despite a decreased in PaCO2 This time window 'free' from hypercapnia might allow to propose the concept of 'CO2 dialysis'.
